Detector of living tissue strength and electrical resistance and activity

Abstract

A diagnostic cylindrical probe introduced through the body surfaces to the target tissue to detect the resistance of the tissues to piercing, its electrical activity and its resistance to passage of electrical current to identify the nature of the tissue and predict the nature of its pathology during needle biopsy has a sharp piercing tip attached to its end through a coiled wire to slide over the surface of an inbuilt changeable electrical resistance incorporated in an electrical circuit to detect the mechanical resistance of the tissues to piercing, a sensor at its tip incorporated in a second electrical circuit to detect the electrical impedance of the target tissue and a secondary electrically isolated sensor incorporated with the first sensor in a third electrical circuit to detect the electrical resistance of the tissues to passage of electrical current.

Description

BACKGROUND OF THE INVENTION1. The Old ArtTissue biopsy is essential for many studies including histopathological, Immunohistological & histochemical studies.Biopsy can be done by a biopsy needle with a sharp edge to cut the sample & carry it out side the body. In the needle biopsy metal sheath passes an internal metal needle to allow piercing of the overlying tissues.2. Defect in the Old ArtThere is no sure sign that the tip of the needle has arrived to the target tissue this depends partially on the accuracy of the imaging technique & the experience of the operator, there is also a delay in the diagnostic results.It is not uncommon that valuable days are lost to receive a pathological report of failure to take the biopsy from the target tissue.BRIEF SUMMARY OF THE INVENTIONThis apparatus is used during needle biopsy where it is introduced in the needle biopsy sheath instead of the needle to observe measure or record the resistances of the tissues to piercing, its resistance to pass...

Problems solved by technology

There is no sure sign that the tip of the needle has arrived to the target tissue this depends partially on the accuracy of the imaging technique & the experience of the operator, there is also a delay in the diagnostic results.

It is not uncommon that valuable days are lost to receive a pathological report of failure to take the biopsy from the target tissue.
